These examples demonstrate using the Electrostatics, Boundary Elements interface, introduced in version 5.3 of the COMSOL Multiphysics® software. In the blog post associated with these files, "How to Create Electrostatics Models with Wires, Surfaces, and Solids", we demonstrate the pros ... En savoir plus
An automotive midwoofer is modeled using the lumped parameter approach. The electrical and mechanical components are modeled using a lumped electric circuit, which is coupled to a finite element model for the acoustics using the Lumped Speaker Boundary feature. The large signal ... En savoir plus
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. En savoir plus
Electroporation is a technique where a localized electric field is used to generate nanometric pores in cell membranes, improving the cell permeability for ions and pharmaceuticals. This model shows the electroporation of a spherical cell by means of a nanosecond electric pulse. The ... En savoir plus
The design of antireflective coating plays an important role to increase the transmission of the infrared light that propagates through optical structures such as lens and windows. In this model, we showcase how different bulk structures such as Si and CZT that has the bulk ... En savoir plus
This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. En savoir plus
The katana is a legendary Japanese sword used by the samurai in olden days. Here, we present a simple model where we simulate a differential hardening process to explore some of the features of the katana.

This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radiofrequency Tissue Ablation Using Simulation". En savoir plus
Light collimation or focusing is a basic task often needed when working with lasers in the lab where singlets are used due to their simplicity. If a plano-convex lens is used for the task, there is a correct lens orientation that minimizes aberrations. A useful rule-of-thumb is to ... En savoir plus
Electrical cables, also called transmission lines, are used everywhere in the modern world to transmit both power and data. These cables carry electromagnetic energy, but instead of dealing with the full complexity of the electromagnetic fields, they are more commonly classified ... En savoir plus
